Answer: From what I notice, it's three words: página, relación y gráficos.
Explanation: From the text that you gave us, I noticed that most of it was well written, as far as spelling was concerned, but that some of the words within the two paragraphs were missing accent marks.
The three that I found are the following:
1) pagina ⇒ página
2) relacion ⇒ relación
and lastly,
3) graficos ⇒ gráficos
Hope this helps you out!
(PS, for future reference, I would recommend that you clearly state the question in the header of the problem and simply copy and paste the text/paragraphs into the body/explanation section. I had trouble figuring out what exactly you were asking when it came to this question, so I hope I was able to answer everything. If not, simply let me know!)
